Basic principle of time-varying meshing stiffness of spur gear

The dynamic excitation caused by the time-varying characteristics of meshing stiffness during gear meshing is called stiffness dynamic excitation of gear meshing, also known as stiffness excitation. This kind of excitation is one of the most important and basic dynamic excitation in gear transmission system. This section will explain...

Calculation method of meshing stiffness of gear teeth

Taking straight teeth as an example, the basic concept and properties of gear meshing stiffness are explained. Tooth meshing stiffness refers to the comprehensive effect of tooth pairs participating in gear meshing in the gear meshing area (segments A-D in Figure 1), which is mainly related to the elastic...

Meshing principle of spiral bevel gear

The gear meshing principle, namely the conjugate surface principle, is the basic method to study the contact transmission of two conjugate surfaces. Different from the meshing principle of other types of gear transmission, the contact surface of spiral bevel gear transmission is local conjugate, strictly speaking, it is point...

Helical gear meshing

In the process of helical gear meshing, the humidity of helical gear surface is composed of ambient temperature, helical gear body temperature and instantaneous temperature of meshing contact area. At high speed and load, the instantaneous temperature rise at the meshing point is very high. Gou Xiangfeng et al....
